Has anyone hooked their DX to a PC (XP or Vista) with the USB cable yet? Does DX have the same issues that K2 had, ie, have to use the ports on the back of the PC or use a double ended USB cable to attach to 2 front USB ports? Any new oddities?

I didn't have an USB problems with the K2, so I can't say if the KDX attached to such a port works any better or worse.

I did have the KDX reboot itself when I unplugged it from the USB and then quickly plugged it back in when I realized I still wanted to use it. I think I just caught it when it was coming out of USB mode and crashed it. I don't recall the K2 ever doing that.

Someone correct me if I'm wrong, but the USB 2.0 standard limits a single port to 500 mA of current. My DX wall plug is specced at 850 mA, so I assume the DX needs >500 mA to charge. So IF your USB ports adhere to spec, you will need to use more than one port.

However, in some cases if your ports are limiting to 500 mA, you can run some software that will send a command to increase the port output. I know this is possible in Linux, I don't know about Windows, and I don't remember how either way.

But in ANY case, most ports in new (<2 years old) computers will generally put out much more than 500 mA without even being asked to.

Personally, I have an Eee 1000HE and am currently charging my DX from one USB port and my BlackBerry from another. It seems to be working fine, so far...

You're right and wrong. The Kindle charges faster from the wall plug is all; from USB it asks for less amps and thus takes longer the charge.

Ah, yes, this is true... but there is a lower limit below which the DX will not charge. For example, if I charge from USB with my Eee awake, the DX charges fine. But if I do so with my Eee in suspend mode, the "charging" light on the DX flashes on and off, and as far as I can tell no (or very little) charging occurs. The obvious reason being, less current is available in suspend mode.
